ABSTRACT
Electronic processing is attracting research and development of the enabling technologies for mitigation of impairments at the receiver as equalizer and at transmitters as predistortion. They are thus very important to long-haul transmission systems and networks as well wide-area networks in which the equalizers can be placed at the optical receiver to adaptively equalize any distortion due to different hops in the transmission path in all-optical networks. This chapter introduces the basic concepts of equalization and then gives a case study of equalization of duobinary and minimum shift keying (MSK) modulation formats.
